Abstract

PURPOSE:To enable exact change-over to be performed, by performing change- over to a control unit on the waiting side, after the fault of pulse shift or the like is eliminated by an actually selected control unit in case that an abnormal state is generated. CONSTITUTION:When a device is operated with a control unit 41 and when an abnormal state is generated with the control unit 41, then by the control unit 41, protection working for setting main circuit current to be zero immediate ly (for example, pulse shift) is performed. After it is confirmed that the main circuit current=0, 'abnormal state' is informed to a control unit change-over circuit 43 by the control unit 41. Then, from the control unit change-over circuit 43, after a fixed confirmed time, the output of signal 'selection' is directed to a waiting side control unit 42, and the output signal c2 of the control unit 42 is selected as the output signal d of the control unit changeover circuit 43.
